또한, 현가장치는 구동 바퀴에 발생하는 구동력이나 제동할 때에 각 바퀴에 발생되는 제동력을 차체에 전달함과 동시에 선회할 때의 원심력에도 견디고, 각 바퀴를 차체에 대해 바른 위치로 지지하는 역할을 하도록 되어 있다.In addition, the suspension system transmits the driving force generated on the driving wheels and the braking force generated on each wheel when braking to the vehicle body, and also withstands the centrifugal force when turning, and supports each wheel in the correct position with respect to the vehicle body. It is.

특히, 현가장치는 노면에서의 충격을 완화하기 위해 상하 방향의 연결이 유연하여야 하며, 바퀴에서 발생되는 구동력과 제동력 및 선회할 때의 원심력 등을 이겨낼 수 있도록 수평 방향의 연결이 견고하여야 한다.In particular, the suspension system should be flexible in the up and down direction to alleviate the impact on the road surface, and the connection in the horizontal direction should be strong to overcome the driving force, the braking force and the centrifugal force when turning.

한편, 현가장치는 차체프레임에 충격흡수장치를 매개로 하여 고정설치되어 있는 바, 이러한 충격흡수장치 의해 연결설치된 현가장치는 견고하고 구동바퀴에 의해 전달받는 충격을 유연하게 흡수하도록 되어야 한다.On the other hand, the suspension is fixed to the body frame via a shock absorbing device, the suspension device connected by the shock absorbing device should be rigid and flexible to absorb the shock transmitted by the drive wheels.
